Ig index evolution in cases and controls during the long-term phase post-infection. (A-C). IgG, IgM, and IgA index respectively (measured with Luminex assay) in cases (orange) and controls (green) at 4-6 weeks, and 3, 6 and 9 months after SARS-CoV-2 infection. The box horizontal middle line represents the median, the extremes represent lower quartile (Q1) and higher quartile (Q3); maximum and minimum values (without outliers) are represented by the horizontal lines in the extremes of the whiskers. The individual values between quartile 1 and 3 are represented by dots; the mean is represented by an “x” symbol. For all panels significance levels are marked as *p ≤0.05, **p ≤ 0.01, ***p ≤ 0.001, ****p ≤ 0.0001, ns: p>0.05. In (A) (IgG index) there is an extreme value that has not been represented at 4-6 weeks for P9, (IgG index 16.7). In (C) (IgA index) there is an extreme value that has not been represented at 4-6 months after the infection (P24, hypoxemic pneumonia; IgA index 16.1).
